An Exact Diagonalization Study of the Anisotropic Triangular Lattice Heisenberg Model Using Twisted Boundary Conditions

Mischa Thesberg, Erik S. Sorensen

The anisotropic triangular model, which is believed to describe the materials Cs${}_2$CuCl${}_4$ and Cs${}_2$CuBr${}_4$, among others, is dominated by incommensurate spiral physics and is…
